Need id assistance for JNU Plant 130415SP1-4 : 8 posts by 5 authors. Attachments (4)

I need id assistance of following images belonging to Ruellia sp? (Acanthaceae)
Locality: JNU New Campus
Corolla: caducous in nature; white

Dipterocanthus sp.

Ruellia species in eFloraofindia (with details/ keys from published papers/ regional floras/ FRLHT/ FOI/ Biotik/ efloras/ books etc., where ever available on net) 

Now all Indian Dipteracanthus fall under Ruellia only.

My guess is Ruellia suffruticosa Roxb., but I am not confident, for one more species, R. patula Jacq. needs to be considered. Attached here record by Haines. R. patula unlikely to be found in the region as per FBI and also that FBI thinks R. patula is similar to R. prostrata.

Well, something more….. I missed the BSI checklist

R. patula, I think, can be skipped –Plant illustrations
Instead, there is one R. pseudopatula in BSI –

I w’d like to see better illuminated photos photos of habit and leaves, and comment regarding hairs. As for the color, pure white flowers I have recorded in R. prostrata, but here leaves in the specimen seem different !

Looks like Ruellia sps only. Could be R.patula.  But not able to check all the characteristics from the photographs.

Attached here what had been identified, in this group, as Ruellia prostrata Poir. Flower colour usually not white, may turn whitish sometimes. In the 4th pic you see flower and foliaceous bract sizes.

Ruellia suffruticosa Roxb.

Ruellia patula Jacq.

Ruellia pseudopatula Ensermu

white, maybe pale-purple, corolla 50-57 mm long, 25-32 mm diam., narrow part of the tube 18-26 mm


sepals 5-6.5 mm

ref. Haines

pale blue-lilac or pale purple, corolla 25-38 mm long, lower cylindrical portion is shorter than the upper;

style 16-19 mm long

should be equal to next sp.

ref. Ensermu Kelbessass

pure white, corolla 45-60 mm long, lower cylindrical portion of the tube is longer than the enlarged upper portion;

style 35-40 mm

calyx tube 1-1.5mm, lobes 4-5mm

ref. Ensermu Kelbessass

This species in this thread is Ruellia pseudopatula Ensermu

I am expecting some response from …

… many many thanks for your id assistance along with detailed key.

Thank you very much Sir for your kind response. But I expected you or other member(s) would ask/query why your specimen can not be R. suffruticosa Roxb.! More so because petals and sepals are more or less of equal length in both the spp., (R. suffruticosa Roxb. and R. pseudopatula Ensermu); including narrower to inflated part of corolla tube!
I am explaining why I choose one of the above two ids. In suffruticosa, leaves are 2-5 inch (50-127 mm), while in pseudopatula leaves are 15-30 x 10-20 mm. Comparing the flower size with the leaves in the attached photographs of this specimen I think it would go more with R. pseudopatula Ensermu.

This was clicked at the Rao Jodha Desert Rock Park at Jodhpur in March 2018.
I guess it is Ruellia patula. Could the experts validate?

To me looks more close to images at 

Rather than those at

Thank you … for your feedback.
I had based my ID on the Rao Jodha Desert Rock park brochure which lists the plants in the park. The brochure is available here. The plant guide is available here.
Would await further feedback on the ID.

Images at plant guide link provided by you are not diagnostic as it does not show the side view of the flower tube.

This herb is from Sariska Tiger Reserve
Photo taken on 26-7-09
I think this is from convolvulaceae family
Please id this plant

… the flower texture (vague reasoning) reminds me of Ruellia related species.

Thanks … for taking lead, can it be Ruellia humilis Nutt.?

This is a Acanthaceae member…Please see in Dipteracanthus Genus….

also check Dipteracanthus suffruticosus if it matches.

Pl. also check images at Ruellia patula Jacq.

Wild herb in the coastal sand; Dwaraka (Gujarat)

Ruellia patula ??

I am doubtful with images at Ruellia patula

It also seems somewhat similar to Ruellia pseudopatula, but does not seem to have distribution in the area.

Any other close species ?

Noted. You are right

As per Flora of Rajasthan it Is Ruellia patula var. alba (Saxton) Bhandari,
Flowers closed in sunlight.

Almost close.

Yes, may be Ruellia patula only as per details and references herein.

Taking it as Ruellia pseudopatula, as per images and details herein.

pls help in identification. Small herb Clicked on kondapalli fort, Andhra Pradesh 2015 May

Check Dipteracanthus species

Dipteracanthus patulus

Dipteracanthus prostratus (Poir.) Nees ??

I agree with … for Ruellia patula Jacq. rather than Ruellia prostrata Poir. as per images and details herein.

Yes it’s Ruellia patula, I too agree with you, …

R. patula or R. pseudopatula ?
White. In image ‘original2’ narrow tube does look longer than wide tube, and calyx is not seen hinting its very small size … all points hinting at R. pseudopatula.

TO me its a toss up between R. patula and R. psuedopatula since as a scientists we should need a more precise way of measuring and judging the length of the tubes and since the maker of the pic has torn it from the plant anyway, it should be stripped of the leaves and sepals and put alongside a ruler in the photo.
Please look at … submissions. we need to emulate his photo techniques for details

I will go with Ruellia patula rather than Ruellia pseudopatula as per keys and details herein.

Taking it as Ruellia pseudopatula, as per images and details herein.

I am not sure yet sir will check into this again and will email on this thread

Image 4 better depicts the corolla tube, for this purpose.

Ruellia patula,

Pl. see this attached image from the set.

Ruellia pseudopatula. No doubt about it. Abundant in SavarKundla (GJ), I’m very familiar with it .
